Journal of Fish Diseases, Volume 47, Issue 10, October 2024.Abstract Alternatives to conventional chemical treatments for parasitic diseases in fish are needed. Microalgal‐sourced fatty acid ethyl esters (FAEEs) have shown an antiparasitic effect against Gyrodactylus turnbulli infection in guppies. Here, we tested a range of commercial FAEEs of various carbon chain lengths and unsaturation levels against two ...

Journal of Fish Biology, Volume 105, Issue 3, Page 975-987, September 2024.Abstract Elasmobranch populations are in steep decline mainly due to overfishing bycatch, but parasites may accelerate the collapse of vulnerable and/or highly parasitized species. We therefore studied metazoan parasites of Rajidae from the northeast Atlantic: vulnerable Leucoraja fullonica, near‐threatened Raja brachyura, Raja clavata, Raja ...

Amino acids ofDiclidophora merlangi(Monogenea)
Parasitology, 1975 The level of free amino acids inDiclidophora merlangiis high, comprising over 500 μmoles/g ethanol extracted dry weight. A single amino acid, proline, constitutes some 70% of the total pool. Analysis of parasite protein and host blood and mucus revealed low proline levels, suggesting that the high free pool content was not related to a requirement for ...

Oxygen uptake byDiclidophora merlangi(Monogenea)
Parasitology, 1974 Diclidophora merlangiwas found to consume oxygen under a variety of experimental conditions. TheQo2of homogenates was 0.415 μl oxygen consumed/mg wet wt/h. Oxygen uptake was reduced in the presence of inhibitors: cyanide 0.1 mM and 5.0 mM, 100%; rotenone 10−6M, 56%; antimycin A10−6M, 63 %; malonate 10 mM, 36 %; arsenite 5 mM, 46 %; fluoroacetate 5 mM ...
